How would 1M usd would affect the price? We are talking billions here. BILLIONS!
Yes we are
talking billions, but what's really involved? What do you think a marketcap of billions really means?
It is just a number. As such it is mostly meaningless, though it can be useful when comparing the market cap of bitcoin with that of other coins. Obviously, there are no hundreds of billions invested in bitcoin or any other coin, which is what some people think market cap shows. Some people bought bitcoin when it cost literally cents, some people didn't buy it at all. And if we count only what was actually invested minus disinvested later at whatever price, the number should be much smaller. Maybe, on the order of a few billion dollars all in all.
I agree, the true market cap is surely nowhere near as high. There's may not be as much money in Bitcoin/Crypto as people think there is. I suspect that even daily volume is just as blurry.
